The weighted average atomic mass of Silicon is 28.1
(27.98 x .9223) + (28.98 x .0468) + (29.97 x .0309)
= 25.81 + 1.36 + .93
= 28.1
Explanation:
RAM={mass number ×relative abundance (%) + mass number ×relative abundance (%)} ÷100%
so take (91.05×20) +(8.95×22)
The phrase that describes the energy of collision is D. kinetic energy transferred when billiard balls hit each other.
<h3>What is collision?</h3>
collision can be regarded as coming together of one solid or direct impact to the other such as car collided with a tree.
Therefore, kinetic energy transferred when billiard balls hit each other is an example.
